| 121 | Hermetic motor-driven compressor | JP14537996 | 1996-06-07 | JPH09324781A | 1997-12-16 | TAKEUCHI YOSHIHARU; ABURAYA SEIJI; NOZU TOSHIHARU; TSUBOKAWA MASAHIRO; SAKAI MANABU; AOSHIKA MASAHARU; NARITA TSUGUYOSHI |
| PROBLEM TO BE SOLVED: To prevent a hermetic motor-driven compressor from generating abnormal abrasion and the abnormal sound of a gear pump by influence of the whirling of a crankshaft end part. SOLUTION: Only gear pairs 52 are installed in a pump case 51, and since the other constitutive part of a gear pump is arranged in a position opposed to the gear pairs by sandwiching a cover plate 5, a distance between a sub- bearing part and the gear pairs 52 of a motor-driven compressor can be set shorter than the constitution of the gear pump by a conventional technology, and whirling of a tip part of a crankshaft 2 can be restrained small.

| PURPOSE: To maintain the constantly smooth movement of a vane while low by separating muddy water from the slurry discharged from a pump, and performing sealing and lubrication between each guide groove and a vane with this muddy water. CONSTITUTION: A rotary discharge-feed pump lubricating device is provided with a separating means 30 for separating muddy water from slurry discharged from the discharge port 21c of a vane type rotary discharge-feed pump 20. A rotor 22 is provided with a pressure chamber 22c, and this pressure chamber 22c is connected to the inner end of each guide groove 22a. The muddy water separated by the separating means 30 is fed to the pressure chamber 22c. When the rotor 22 is rotated, the volume of an operating chamber C is expanded- contracted, and in association with this, slurry and the like are sucked from a suction port 21b and discharged to the discharge port 21c. The slurry and the like are thereby prevented from flowing into the guide groove 22a from the operating chamber C, and lubrication between the guide groove 22a and the vane 23 is performed.

| 124 | Two-shaft vacuum pump with suction chamber | JP27511989 | 1989-10-24 | JPH02153292A | 1990-06-12 | BERGES HANNS-PETER DR |
| PURPOSE: To enable solid particles immersed into a pump to deposit in a suction chamber by forming an opening of a scavenging gas conduit at the pressure side of the suction chamber in a pump in which engaged rotor pairs cooperate with a suction chamber wall, and a suction side and a pressure side are formed. CONSTITUTION: In a three-staged vacuum pump 1 with three pairs of rotors 4, 5; 6, 7; 8, 9 arranged axially on two shafts 2, 3, each pair of rotors comprises engagement portions 41, 42 and notches 43, 44 respectively supported in suction chambers 11, 12, 13 for rotating synchronously in a non-contact manner. The rotors 4, 6, 8 are controlled by inlet openings 32, 35 and the other rotors 5, 7, 9 are controlled by outlet openings 33, 37. A suction side 47 and a pressure side 48 are defined by each of the rotor pairs. In this case, an opening 49 of a scavenging gas conduit leading to a gas bomb is formed in the vicinity between gap seals between the two rotors in the pressure side 48 of each suction chamber 12, 13.

| 125 | Gear pump | JP15983482 | 1982-09-14 | JPS5949384A | 1984-03-21 | KAWAKAMI MASARU |
| PURPOSE:To efficiently exclude foreign matter contained in fluid, by forming a groove extending from a tooth end of a gear to a portion near an axis of the gear on a surface of a pump chamber opposed to a tooth side surface. CONSTITUTION:Grooves 14 are formed on surfaces of a casing 4 and a casing cover 5 opposed to tooth side surfaces of gears 7 and 8. Clearances 15 are set to such a value as to be required for rotation of gears in disregard of fine particles. Although the fine particles contained in liquid to be fed tend to enter the clearances 15 during suction to discharge, they enter the grooves 14 as soon as they are sucked through a suction port 10 because the grooves 14 are arranged near the suction port 10, thereby preventing resistance to rotation of gears. Entrance or accumulation of fine particles in the clearances 15 at a portion without the grooves 14 is anticipated, however since the fine particles enter the grooves 14 every rotation of the gears 7 and 8, and are scraped by edges of the grooves 14 thereby to be sequentially excluded with rotation of the gears. Further, as the grooves 14 are arranged at an angle to the rotational direction of the gears 7 and 8, the scraped fine particles are induced toward the tooth end, and readily enter a liquid well 16, thus efficiently excluding the fine particles. | ||||||

| A fluid pump includes an inlet plate with an inlet; an outlet plate, the outlet plate having an outlet plate outlet passage; an outlet; an electric motor having a shaft which rotates; a pumping element coupled to the shaft such that rotation of the pumping element by the shaft causes fluid to be pumped from the inlet to the outlet, the inlet plate interfacing with the pumping element in an inlet sealing surface interface and the outlet plate interfacing with the pumping element in an outlet sealing surface interface; a purge passage which receives fluid from the outlet plate outlet passage, the purge passage being in fluid communication with the inlet sealing surface interface and the outlet sealing surface interface; and a filter downstream of the outlet plate outlet passage which filters fluid that passes through the purge passage prior to reaching the inlet and outlet sealing surface interfaces. | ||||||
| 128 | POSITIVE DISPLACEMENT TRANSFER GEAR PUMP FOR MOLTEN METAL | US15431581 | 2017-02-13 | US20180230995A1 | 2018-08-16 | Bruno H. THUT |
| A self-cleaning transfer gear pump for transferring molten metal includes the following features: a transfer conduit extends upward from an outlet of a base, two rotatable gears are formed of refractory material and disposed in the gear chamber and engage each other during rotation. A boss functioning as a bearing extends from the drive gear and is adapted to be received in an opening in the base. A shaft is fastened at a lower end to the drive gear. A filter is fastened to the base so as to cover the inlet and prevents particles and objects in the molten metal from entering the gear chamber. In operational mode, a motor rotates the shaft and the drive gear whereby the drive gear and the second gear engage each other while being rotated so as to positively displace molten metal from the inlet to the outlet and along the transfer conduit to the remote location. In self-cleaning mode, the motor rotates the shaft and the drive gear effectively to draw molten metal from the transfer conduit by positive displacement, through the outlet, and toward the inlet therefore cleaning the filter by removing the particles adhering to the filter. Also included are a system with optional filter and optional self-cleaning mode but including an inlet portion of a die casting machine, and a method for operating the gear pump. A flow sensor may be used to transmit pulses into and from the transfer conduit so as to enable determination of a volume of molten metal being charged. The control of the molten metal volume being charged is not solely controlled by the flow sensor. | ||||||

| An internal gear pump with a field replaceable idler is disclosed that may be used for sanitary applications. Access to the idler mainly merely requires removal of the head. Access to the seal assembly disposed at the inboard end of the pump chamber is also fast and easy as removal of the head exposes a fastener that secures the rotor to the drive shaft. Removal of this fastener enables the rotor to be removed with a standard rotor-pulling tool thereby exposing the pump chamber seal assembly, which may be cleaned, serviced or replaced as needed. | ||||||

Using one of the covers, the rotary lobes can be vertically removed and maintained without having to dismantle other pump components from the pump housing. The rotary lobes can also be removed together with the angular gear as an integral pump component using one of the covers. | ||||||
